Abstract

Die Erfindung betrifft eine Bohreinrichtung (1) zur Bearbeitung spröder Werkstoffe. Hierbei ist ein Bohrkopf (2) mit einer Bohrstange (3) zur Übertragung des Bohrmomentes lösbar mittels einer formschlüssigen Verbindung verbunden. Zur exakten relativen Ausrichtung hat der Bohrkopf (2) eine kegelförmige Ausformung (10), die im dargestellten Betriebszustand zentrisch in eine entsprechende Aufnahme (11) der Bohrstange (3) eingreift. Zum Schutz gegen axiales Lösen dient eine als Hohlmutter ausgeführtes Fixierung oder Arretierung (15; 20), welches in jeweils ein Gewinde (16) des Bohrkopfes (2) und in ein Gewinde (17) der Bohrstange (3) eingreift, wobei die Gewinde (16, 17) zueinander gegenläufige Steigungen aufweisen. Durch eine Drehbewegung der Arretierung (15) können der Bohrkopf (2) und die Bohrstange (3) daher in einfacher Weise gegeneinander verspannt oder zum Austausch auseinander gezogen werden, wobei zugleich die von der Arretierung (15) eingeschlossene Verbindung vor äußeren Einflüssen optimal geschützt ist. Die Bohreinrichtung (1) ermöglicht daher Bohrungen mit hoher Genauigkeit, ohne daß hiermit zugleich ein erhöhter Verschleiß oder eine umständliche Handhabung verbunden ist.

Figure 00000001
The invention relates to a drilling device (1) for processing brittle materials. A drill head (2) is detachably connected to a drill rod (3) for transmitting the drilling torque by means of a positive connection. For exact relative alignment, the drill head (2) has a conical shape (10) which, in the operating state shown, engages centrally in a corresponding receptacle (11) in the drill rod (3). To prevent axial loosening, a fixing or locking device (15; 20) is used, which engages in a thread (16) of the drill head (2) and in a thread (17) of the boring bar (3), whereby the thread ( 16, 17) have opposite slopes. By rotating the locking device (15), the drill head (2) and the boring bar (3) can therefore be easily clamped against one another or pulled apart for exchange, while the connection enclosed by the locking device (15) is optimally protected from external influences , The drilling device (1) therefore enables holes to be drilled with high accuracy, without at the same time being associated with increased wear or cumbersome handling.
